如何实现的呢
ruby 代码解析库 => AST
ParseTree • 最早的 ruby 代码解析库 • 不⽀支持 ruby 1.9 和后续版本
ruby_parser • 最流⾏行的 ruby 代码解析库 • 输出结果和 ParseTree ⼀一致
None
None
ActiveRecord::Base belongs_to :user touch :archived_at def archive
ripper • ruby 内置的解析库 • ⽀支持 ruby 的新语法
None
ActiveRecord::Base belongs_to :user def archive touch :archived_at
parser • 新的 ruby 代码解析库 • ⽀支持代码重写
None
ActiveRecord::Base belongs_to :user def archive touch :archived_at
